[@sadhanapatel1462]

Thank you bhaiya

[@warfarecreations379]

Underrated

[@ravikantmaurya1979]

Whenever I stuck at any problem I directly jump to your videos.....Really it's a very good way of explaining the things.....continue this

[@seesagar]

😁Thank you

[@manavmody4959]

Your videos ensure the best solution and explanation. No need to watch other solutions!
But sir, i always end up watching the solution as i am unable to solve the DSA problems by my own.. Is it normal?

[@shashwat_tiwari_st]

Thanks 😃, yeah don't worry it's very normal. Coding is something which will require a lot of practice, you just have to keep practicing. Best of luck ✌

[@rohandevaki4349]

you have used the same approach that is written in gfg problem solution?

[@sriramr1981]

How to sort the output in ascending order ji 🙂 Thanks in advance. Please reply me.

[@rachit2982]

Please make a video on "find a specific pair on matrix" it is given on gfg as hard problem

@@shashwat_tiwari_st thank you so much sir 😊😊

[@anorophile2841]

Hi, it's a very nice solution you have provided but your logic is not working for inputs such as 1 2 1 2 , 2 2 2 1 , 2 1 2 2, 2 1 1 1

[@sadhanapatel1462]

Time complexity nhi bataya aapne

[@pushkarsharma5447]

sir if I want to solve without data structure how to do plz make videos

[@shashwat_tiwari_st]

Okay, I will share a self explanatory code with you.

[@pushkarsharma5447]

Ok

[@shashwat_tiwari_st]

@@pushkarsharma5447 github.com/Tiwarishashwat/InterviewCodes/blob/main/CommonMatrixElements.java see the 2nd code, it is without data structure. The approach is similar to the one discussed in the video.

[@pushkarsharma5447]

Thanks bhaiya
Code in c
#include
int seen(int array[],int element,int end)
{
for(int i=0;i

Bhai actually I am mtech datascience iit g student I am from mechanical branch in btech so If u can share something thru which I can clear my doubt from u
Thanks in advance
